nice tidy cuts in the right place are always good, but dont over do it dave clarke style.
spin backs are cool, eq'ing is a great tool, cutting all the bass out and then bringing it back in always works well.

but like anything, dont over do all this, otherwise it justs gets boring and takes peoples attention away from the music too much, which tbh, is what most people go out to a party for, so yes it is all about the music
